His starting Upgrades let you choose how ‘mad’ you want him to be, as a Gadgeteer inventor, using Fringe Science, or with an endless supply of Master Plans. He also has a Techno-Gadget that can be redirected for different purposes throughout an Adventure, and can be leveled up along with your Hero, using its own mini-Upgrade Tree to unlock the power of Super Science!
