Mighty No. 9

This is best achieved on Seismic's stage. After entering the mine, follow the path and you'll have drill robots going up and down. Weaken them to expose a power boost, then absorb them one by one, waiting as long as possible to absorb the next one. After the last one, there's a forklift bot over a wall that can be used to extend it one last time. This will give you plenty of time to last for a minute.
