Harassing
Mordred @penisenvy
Enjoys the occasional knock-out battle against her; doubly-so enjoys getting her riled up and then showing her up.
Akira Inugami @alwaysgrumpy
Does not dislike him. In fact, you could even say Damian enjoys talking with him; the man has useful things to say.
Davesprite @crowsicle
The faceless voice he sometimes chats with is definitely on the Cool List. Would not be adverse to meeting him in person one day.
Lumina @chaoticwhimsy
Stole his cape. Very troublesome. Wants to impress her.
Edward Nygma @questionslinger
Evidently reformed. Damian is skeptical, and chooses a house as far away from the Riddler as possible. Not entirely adverse to the occasional chess game, however.
The Doctor (Eleven) @gallifreytotrenzalore
This man is not a doctor.
Jason Todd @waywardbird
Castmate. Technically, brother. Hates his future self, but is finding that this Todd is not the same person. Will punch, not stab.
Kuzuryuu Fuyuhiko @pocketmobster
They have a lot in common.
Dirk Strider @thepuppetmaster
Unsure. More data needed. Definitely wearing a boomerang on his face. Mentally referred to as "Boomerang Blond."
Jane Foster @bifroster
Concerned civilian scientist. Damian is attempting to use his manners with her.
Steve Rogers @captain-asthmatic
Not in Damian's good graces. Far too tall. Lines have been crossed.
Arturia Pendragon @untilavalon
Mordred's parent, and King Arthur. Has a powerful presence, and a comfortable shoulder.
Chiaki Nanami @entercheats
How. How did she beat him so badly at his own video game?
Gilgamesh @omnishamble
Who's the adult here, again?
Bucky Barnes @zastyvshiy
Damian doesn't let sleeping dogs lie.
Jack Napier @sickjoke
Todd, Todd that's the fucking Joker-!
Diarmuid Ua Duibhne @oathshackledbird
Grayson might be replaced. Serious case of hero-worship (for Damian) going on here; which means he tolerates and even enjoys the man's company.
The Doctor (Ten) @likesimpossible
Madman with cool alien tech in the library.
