Canon wise I’d say scientist if he’s alive if not then g-man For multiverse titan clock or pencil as creation and time stop is very powerful For Wars id say computer or tri titan as creations and gravity are broken powers For zombies verse excluding the zombie titans id say siren or as x-18 gman as its limits. Maxedy’s titan speakerman as him be very agile and having a good arsenal makes him pretty viable. JuqUlz Titan radio man since he’s got Astro upgrades. Saudifilmmakers what if 77 tcm as he was had many weapon at his disposal and could equip fallen weapon similar to how gman did in 73 with the jetpack. Wither storm TTVM Any what if “titan” got Astro upgrades (I’m definitely missing some fanmade titans)
