The newest update dropped Lumi and Finx, and they're honestly some of the most fun characters I've played with in brawl games. Lumi's this rock drummer who attacks with these cool dual-element combos - like hitting with a fire drum beat then following up with an electric guitar riff that bounces between enemies. Finx is more tactical - he can actually mess with time to slow down enemies or speed up teammates. Super handy in team modes! They also brought back Cornelius and Doug with some improvements, and completely reworked Kenji and Moe to make them actually worth using.

The seasonal stuff is pretty impressive too. The Halloween content went all out with these eerie skins - that Possessed Poco one changes his attack animations to these spooky ghost notes, and Skeletal Surge looks wild with his glowing bone mech suit. That UNO-themed mode is weirdly addictive - you're fighting while playing UNO cards that can flip enemy attacks or make them miss turns. And unlike the regular game where it costs actual money, the Pro Pass is totally free in Nulls Brawl. All those fancy Pro Skins are unlocked immediately - I'm particularly into the Astral Colt skin with those space effects and animations. Having everything just available without grinding or paying actually makes the whole experience way more enjoyable.
