This is Billy Kaplan/Wiccan from Young Avengers who will basically react like Teddy, minus the whole 'posing as you one time' thing.
On ~female_archer I have Kate Bishop/Hawkeye from Young Avengers/Hawkeye who will tell Peter Parker what's what when asked...and sometimes when not asked.
And on ~now_oracle is Barbara Gordon/Oracle, resident information guru/computer genius.
