Oh, this takes me back! I was deep into the Ultimate Universe when Marvel was reinventing their classic characters, and 'Ultimate Spider-Man' was my absolute favorite. Now, Power Man—aka Luke Cage—wasn't a central figure in the early issues, but he did show up later in the series, especially when the Ultimates (that universe's Avengers) got involved. His portrayal was grittier, more street-level, which fit the Ultimate Universe's edgier vibe.
What's interesting is how his dynamic with Spidey shifted. They weren't instant buddies like in the main universe; there was tension, distrust, even some clashes. It made their eventual team-ups feel earned. Bendis really played with expectations, and Cage's arc—from ex-con to hero—had this raw, grounded energy that the 616 version sometimes glosses over. I miss how unpredictable those stories felt!
