OUT OF CHARACTER ☆
BACKTAGGING: Within reason.
THREADHOPPING: It is better to ask first but it would probably be fine.
FOURTHWALLING: No, please. It's not very likely your character would know much about Eagle anyway.
OFFENSIVE SUBJECTS aka TRIGGERS: Just keep things polite and 'general audience' friendly. 

IN CHARACTER ☆
SPECIES: Human
ABILITIES / SUPERNATURAL POWERS: Eagle has no magical powers but he is from a technologically advanced culture who uses mental energy as a power source. This being the case he wears a weapon on his arm that is capable of producing a shield as well as a laser sword the strength of both of which depends on how much will power is funneled into them. Additionally Eagle can use his willpower to pilot a large, lightening fast, mecha. 
PHYSICAL AFFECTION:Platonic or romantic, all's good with this character.
PHYSICAL VIOLENCE: Eagle can handle himself in a fight but, like with all of my characters, I'd like to discuss things before you character kills mine. 
MIND-READING / TELEPATHY: While people from Autozam do use mental energy to power their machine they are not psychic in any way so he would have no defense to this. He might be able to overcome mind control with will power. That does happen in canon with a few characters.
OFFENSIVE SUBJECTS aka TRIGGERS: Eagle is a fairly easy-going guy overall so I can't think of anything particularly offensive, but he might become sad or wistful when speaking about his home Autozam.

ADDITIONAL NOTES: Not at this time.
