Role- Rival > Future Mate
Name-
Lochkit[paw]
Other- I know that he's younger, but I think this would be interesting ^^ He will be terrified of Falcon due to the fact that his mother killed his father - which is the reasoning for Loch being so timid, quiet, and distrustful of HRs. We could have it be that Falon is aware of this and also uses that to bully, or he could figure it out later on and maybe become regretful of being mean? (whichever you'd prefer)
Role-
Pastblaze
Name- Former (first) Mentor
Other- He could have been Falcon's first mentor, and since Past was a strong EE supporter he could have encouraged Falcon's desire to be like his mother. Though he was killed during the RC Liberation Battle, causing Falcon to need another one.
If you want Falcon to have a Dark Forest mentor, Pastblaze could that~
Locustkit for an enemy (Falcon could take their anger on Locust about Russet replacing Thorn? / Locust will be confused since he doesn't know about Thorn :3)
Verdinkit as a friend (she would only be interested in befriending him due to his mother instead of personality)
Jaggedkit as friend (same reason as Verdinkit at first, but would actually see him as a friend / may be a bit cold when Falcon finds a male mate, but would get over it... eventually)
Dovepaw as "friend" (same reasoning as Verdinkit / won't have really any loyalties to him if something goes wrong in his life, but may act kind towards him at times)
