Today's Fact
He accepted Earth's Mightiest invitation with a king's smile — and a spy's notebook open under the table.
When T'Challa journeyed from Wakanda to New York and joined the Avengers in The Avengers Vol. 1 #52 (1968), readers saw a heroic king answering Captain America's recommendation and taking his place among Earth's Mightiest Heroes. What nobody on the team knew was that the Panther had accepted the seat as an intelligence posting: he was there to watch them.
Christopher Priest's Black Panther Vol. 3 run (1998) spelled out the motive decades of stories had left politely vague. T'Challa's father had taught him that Wakanda survives by being prepared, and the Avengers — a team that could level a city before breakfast — were exactly the kind of power a hidden nation needed assessed from the inside, at close range, by its own king.
The mission quietly failed in the best possible way. The longer the Panther served beside them, the more the supposed threat became comrades he trusted with his life — and who trusted him with theirs, eventually asking him to lead the team. The spy Wakanda sent into Avengers Mansion ended up one of the Avengers' own chairmen, which is a strange outcome for an infiltration.
