Is Starlight - Billy Kid good?
A Physical Rupture agent who fights from a motorcycle with drifts, flips and wheelies. He spends HP to build Determination (up to 120), heals it back, and spends 100 on Full-Throttle Starlight, his heaviest hit, while weaving several Specials and EX Specials. He bursts hard in stuns and keeps up decent damage outside them through Cool Wheelie, which suits fights like Thrall, and his Core Passive makes substats forgiving.
He drops off more than almost any agent outside his best team, his damage is spread across many skills, and his animations are very long.
Strengths
- High stun burst and decent damage outside stuns
- Forgiving substats
- Varied, fun moveset
Weaknesses
- Huge drop outside his best team

Billy Kid/Lore
"Huh? Billy's new equipment? He has been bugging me about getting an advance on his income to buy some big-ticket item, probably one of those limited-edition or discontinued paraphernalia or life-size collectible things again.
I just hope he doesn't put it in our living room.
I don't have time to deal with this right now.
I'm working on closing this major deal—"
Nicole, whose voice suddenly gets cut off on the other end of the line
"His new form? Yeah, I kinda expected it...
But man, one thing did catch me off guard — he still remembers the red scarf."

"Wait, so you're saying your new equipment can turn into guns, cannons...
anything at all? Really? Then can it dispense mackerel?!
No...? How boring."
Nekomata, who gave Billy's equipment explanation trial a feedback score of 0
"You think Starlight Knights are only born from the chosen few?
Wrong. As long as you hold courage in the face of darkness, the starlight shall answer your call!"

I was tryna go for something way cooler and more hype with like explosions and AHHHHH is my time almost up?!
O—Okay, I gotta strike my coolest pose!
