Donut's Relationships

Donut has relationships with many of the Red vs Blue characters.

Blue Team
Everyone seems to like Donut beliving him harmless except Tex due to him killing her.

Church
Church has nearly no interaction with Donut except when Church tries to kill him to stop Tex's death. Later in Season 5 he tells the Reds Donuts his favorite Red and he also belives Donuts armor is "lightish red".

Caboose
Caboose and Donut although being on diffrent teams seem to be great friends.

Tex
Tex and Donut have little interaction. Their main ones being her sticking him with a plasma grenade and him killing her in episode 19 of Season 1. When she comes back in season 2 she refers to Donut as "The bitch who killed me." Donut belives her to be boring in season 3 when her and Shelia talk about girl stuff and not the "fun" girl stuff like ribbons and unicorns.

Sheila
Donuts only interactions with Shelia are when she shoots at Red Base. When she Tucker and Lopez come towards red base to get the reds to turn off their radios.

Red Team
Everyone on red team except Lopez seems to like Donut but get annoyed by him easily

Sarge
Donut and Sarge seem to get along well. Sarge has even claimed to miss Donut after his "death" in chapter 4 of Red vs. Blue: Revelation. Although in Season 5 Sarge belived he had died and gone to hell after falling into the caves and seeing Donut down there.

Grif
Grif seems to not care about Donut saying whats up with everyone likeing Donut after he is crushed by Sisters pelican.

Simmons
Simmons seems to get annoyed by Donut.

Lopez
Lopez hates Donut even going so far as to saying he could kill him this is likely due to Donut providing incorrect translations for what he is saying.

Wyoming
There is no interaction between these two other then when Wyoming shoots the rocket from Tuckers hands.

Washington
Donut doesn't really have much interactions with Washington other then when Wash shot him in Recreation Chapter 19.

Maine/The Meta
Donut doesn't have many interactions with the Meta. In episode 12 of Recreation Donut while cleaning blue base Meta tries killing Donut though he keeps failing. Then he and the rest of the Reds other than Sarge and Grif ran from Meta.

O'Mally/Omega
Despite fighting each other they nearly never meet each other. Only when donuts doing recon in the caves,when he sees O'Mally ordering his robot army (really insulting himslef in spanish) and Donut comments saying How Strange in spanish, and when he is taken over by Omally. It is also worth noting that when Donut first saw O'malley he reffered to him as the "cave devil".
