Midora has quite a few abilities, his most impressive is his Mirror Neurons (Power Copying). . Midora can copy complex abilities like Minority World (which is
Ichiryuu's primary ability) and Food Luck (Joa's primairy ability). He can also use to it become invisible. Please read my stuff below cause I wrote it all myself from my own reading of Toriko
Minority World is basically an abilitie that alters the nature of atoms and make them defy physics. In 100 atoms, 10% (10 atoms) do not behave in natural way and have erratic movement and behavior (such as defying gravity) because of square root law. Minority World turns the minority (10%) of those misbehaving atoms into majority so that all of them show unusual pattern. Minority World can change the texture of ground on atomic level, changing hard rock into soft. It's most dangerous effect on humans is causing organ failures such as heart, lungs, liver, reversal of blood and the shutdown of the entire nervous system. It also slows down the victim's movement and reduces speed stat. Because Minority World affects bodily functions in such a way, it prevents Regenerationn and leads to the victim's death. For it's other uses, Minority World can reverse attacks of the opponent can send them back, used for Regenerationn for the user and levitate by defying gravity. Midora copied Minority World while fighting Ichiryuu and gained resistance to it while fighting.
Food Luck is an ability that makes your opponents attack miss, the probability of your opponents attack is reduced even if it's 100% on target. The most impressive thing about food luck is it's AoE, Food Luck can dodge attacks that are 10x the surface area of Entire Earth. So it makes it nearly impossible to touch Midora until his food luck runs out (the ability is concept based, not energy so it basically grants the user 'luck' or blessing from Gourmet Gods). Midora copied Food Luck after he was sealed in Joa's tuna can.
Now comes Midora's own ability, Hungry Space. Midora can kill opponents on atomic level in a void of space surrounding his opponents. Even if the user can somehow bypass hungry space, Midora can still kill using Hungry Tongue.
He can also paralyze opponents entirely by using Knocking (to show how strong knocking is, knocking can stop the rotation of an entire planet almost instantly, nullifying the kinetic energy)
He also has energy attack with Meteor Spice but energy blasts are too mainstream so I will leave it at that
