Demopan: Works just like regular hale except he has global (partial) blind and you can press R to charge indefinitely (might get stuck charging sometimes)
Gaben/Gangnam Heavy: Works just like regular hale except a bit slower. Using rage will activate Valve Time which allows you to zoom forward when attacking which will 1hitkill anything you hit. Has heavy fists so you can attack while stunned.
Bonk Boy*: Don't remember the stats on this one very much but he at least has jump and 2 lives. Not sure if Voidy took out or tweaked the Soda Popper.
Dic Soup Can*: This boss doesn't come up often I think he's basically like regular hale??
Cave Johnson: He's different in SXH's FF2 than the SXH servers. in FF2 his grenades are more powerful and his rage is extremely high (around 5500-6000 maybe) that summons dead players to blue team instead of gaining a
valvelemon rocket launcher. Hope you're good at lobbing grenades.
Christian Brutal Sniper: He's a little more powerful in FF2 due to one fact: his rage always gives him a full quiver of arrows (instead of n+1) but without arrows he essentially works like regular saxton hale with a much smaller scare radius
Vagineer: Works just like regular Saxton Hale except he has small scare radius and can ubercharge, which is perfect for taking out sentries unhindered if there are no pyros.
Headless Horseless Horsmann jr: This one teleports intead of jumps and is often limited to the floor. But on our servers he can climb walls by hitting them, the jump starts the beginning of the swing and you still deal damage at the end. And the range on that axe omg.
Cuddle Heavy: is one of the more underpowered Hale's because he has zero crowd control. He can play like CBS but he doesn't get a scare.
Painis Cupcake: basically vagineer
Seeman/Captain Falcon: Plays like Saxton but explodes everything around him on rage, dont spam or you'll get many airshotted.
Seeldier + other summon hales: Plays like saxton and gets to summon dead people along with scare rage.
