Beast summoning

Super Nature Guy can summon beasts and animals to do his bidding.

What's his power/power category? I'm not seeing any sort of summoning power on the list. 

Psychic power - Animal Control

Power source - Nature

Archtype  - Minion Maker

Principal - Principal of Fauna 

Animal Control: Your summoned minion is one from the environment that you are controlling for the scene duration

Cold/Electricity/Fire/Weather: You summon an elemental from the environment to aid you for the scene duration

Materials: You temporarily bind a nature spirit into a form of some material, enabling it to assist you for the scene duration.

Edit: I thought you were referring specifically to the Nature Power Source, but it gives you a couple of options to work with. There's also the Minion-Maker Archetype, or the Summoned Allies Red Zone ability. Summoned Allies comes from the Elemental/Energy, Materials, Psychic, and Self Control Powers.

Minion Maker!

That's the missing piece from my equation. Thank you both!

for completness Nature Guy might also want 

Power - materials - plant

Principal - principal of flora

Even if you don't have Minion Maker Archtype you can still get lots of use out of animal control. Natatively you have a pack of wolves as an escort but you have to act on your turn with nature control to have them attack/defend/boost/hinder/overcome for you. They would not be active targets on the feild but a clever enemy could roll to create a "scattered pack" persistant hinder on you to lower your rolls when using your beasts

Duplication Self control power can also be used with out minion maker in this way. Multi Man from Hana Barbera's Imposibles/Super Globtroters was like this- he created copys of himself in collums and rows but they were not independant targets it was almost more like stretching or momentum powers sometimes
