What is your favorite Red, Blue, Green, and Colorless Unit?

Red - can I say Laevatein? If not, Celica.

Blue - Nephenee, with Summer Corrin and Micaiah close seconds

Green - Axura, no competition

Colorless - Kitty Sakura and Performing Olivia, great art for both.

Red-Soleil, favourite fates character to me and she is a beast on player phase

Blue-Nephenee, underrated unit with great def and spd she never fails when i need to kill a lance or sword user also her artwork is gorgeous

Green- Cecilia, she isn't very powerful but with the cavalry buffs and blade tome she becomes a monster, my only 5 star+10 unit

Colorless- Kagero, she isn't my most used colorless unit (brave lyn holds the title) and she doesn't even have my favourite design (because bridelia exists) but she was the first 5 star that I pulled and before the release of the skill inheritance she always helped me to deal with the ryomas and takumis that were very common back in the day so i'm a little fond with her.

Welp, this one is tough, so I'm gonna start with green.

Green: Nino Minino. She's my leader since I started the game, she's almost always MVP, and carried me through most things. If she was real, I'd teach her to read.

Red: Ike. I've really enjoyed him and has always been paired with Nino even before support became a thing. Doesn't help I'm playing PoR right now. Knight Chrom is coming close to take his place because he's just so good.

Blue: Shigure. Although I love Neph Neph, and she's in my main team, Shigure has carried a lot in training units and in doing some real stupid strategies to clearing GHBs (Oliver's especially). Also, his art is simply too pretty. Best male fanservice than B!Alphonse.

Colorless: Takumi and Takumean. Technically the same, only possessed Takumi is crazy. He was my fave in Birthright, and I still love him to this day, even if his lines pain my heart. He may not be the best archer now, but still, good art and voice, and lots of tears for me.

Shout out to Maria and Lucius for helping me in training!

Red - OG Lyn (First 5* I pulled)
Blue - Infantry Ephraim - Such a great buffing unit. Fits on every team.
Green - Rhajat (Green mage and anti cavalry...so fun to use)
Colorless - Faye (Guard Bow, QR, and DD seal...incredible counter to ranged units...and love her art)

Red: Celica. Best girl, no more need to be said.

Blue: LA!Lyn, I put so many orbs into the LA banner for her, I was completely willing to make any amount of sacrifices to make her fantastic. I shredded a Winter Tharja and a Hardin for her. both of which were my only ones. I haven't regretted my decision since, and I really love using her.

Green: Myrrh, I hadn't originally planned to roll for her, but I eventually caved and threw some orbs at the banner so I could earn some new toys for flier emblem. I got her with +atk, -spd, and she is the star of my flier emblem, decked out with DC and QR.

Colorless: This one is a tie. It's either my Genny, who has become really good since 2.0. The Wrazzle Dazzle combo is so great. In fact, she is really good in the current TT, as she can chip away at Grima while keeping on of the purple spikes in between them. The other would have to be Sothe. I really like Sothe as a character, the fact that he strives to do good and protect his friends yet is so humble, and the fact that he is so good in Heroes. In my opinion, he is the best dagger unit in the game.

I have favs, but somehow so many are red...

Olivia (I like dancing), Sophia (cute :3), Sigurd (Holy Diver ?) and Ike (Ya know. We like Ike.)

Blue: LA Lyn
Green: BIke
Colourless: Tie between Azama (he is so beautifully careless...) and Jaffar (this guy is as intimidating as he should be).

Red: Alm

I always had him on my team before his refine as I was hyped for Echoes at the time. Now I've got a destructive dragon slayer thanks to his refine and making use of his Windsweep.

Blue: Berkut

This was after I played Echoes and my goodness did I love the voice acting for him in that game, I always love when Berkut triggers his special in Heroes. I place him on my team when I feel like doing mixed teams.

Green: Hawkeye, this guy has been my saviour against Horse Emblem teams, I made him specifically to deal with those pesky horses and can pretty much survive any attack from them except for red ones, kinda tempted to give him Poleaxe+ from Gerome.

Colourless: Sakura

She was one of the main reason I chose Hoshido first in my first playthrough of Fates. Loved her personality and cuteness and hopefully when I get an extra Genny for Wrathful Staff, she'll be a mainstay on my team, I practically have every available Healer skill on her.

Now that I think about, my choices are characters that people considered mediocre or outclassed by others in this game. (Alm counts because of people's thoughts of him before he got the Double Lion refine.)

Red: Zelgius. Really tanky red armor with fun skills
Blue: Effie, her with distant counter is amazing
Green: Come on, don't make me pick between H!Henry and W!Lissa
Colorless: Clarine, she's been my main healer for a while now, she gets really good with Pain+ and double savage blow

Chrom/Legendary Ike, Reinhardt/Oliver, Hector/Christmas Chrom, and Summer Frederick?

Since I might as well do two colorless, Wrys gets an honorable mention. What a nice old man.

Red I think is Ryoma. Oldest 5 star I have(from back in the first Hero Fest) and he still sees a lot of use

Blue would be Reinhardt(Surprise, surprise, I know) because he's part of my arena core

Colorless is Neko Sakura cause she can cut through any mage.

Green is Fae. Shouldn't need anymore explanation.

Red - Adult Tiki. First red unit I ever pulled and still have her around to this day at 5*+10. The Final merge came around the dragon voting gauntlet.
Blue - Valter - His lines, mostly just his lines.
Green - Julia - at one point my stalker during seasonal banners, but she's been my favorite dragonslayer.
Colorless - Halloween Sakura - Cause she's a cute little kitten.

Red: Eirika. She motivated me to play The Sacred Stones along with Ephraim but I was attached to her since Ephraim went lone wolf and didn't want to appear in every pull I did when he was a focus. When her refinement was announced I was so happy and she's one of my best sword units with the Def Tactic seal.

Blue: Brave Lucina. She's one of the best buffers in the game, even better with Double Tactics (being Atk and Def in her case). I picked her in the CYL and it was one of the best decisions I made in FEH. Also, I wanted a Lucina and I needed a Lance unit, she was the perfect choice.

Green: I think is a tie between Nino and Amelia. Nino destroys almost everything when buffed by Eirika and Amelia because she's so useful in FEH and The Sacred Stones. Also because their art is made by Amagaitaro.

Colorless: Felicia and Sakura. Felicia is my lead, as some may know and I find her character to be funny. When I started the game she was one of the units I used but was sad she wasn't quite powerful until she got a Prf weapon + refinement. Also, I love her "Whoa!" line. Sakura was one of my first healers and once I got a +Atk -Def just in time for her upgrades/refinement, I knew I had to build her up. I don't know why but she makes me feel comfortable.

Red- A. Tiki
Blue- W. Robin
Green- Myrrh
Colourless- Wrys xD
