Everything was going as Onana planned.
For 5 years, apart from spending his time observing and studying the Radiation Space Bugs, he also planned on how he would take over this Planet.
Originally, he thought he would need General Aztog's whole fleet to take over the Planet but the more he knew about the Space Bugs, the more measures he devised in which he could easily take over the Planet.
The Radiation Space Bugs were powerful and numerous but they were divided, this was their greatest weakness to him.
'Divide an conquer, that is the ultimate strategy to steamroll through them'.
Once he arrived at the general plan, he also spent time finetuning it for months before he prepared it to the General. In their estimates, nothing would go wrong and they were right, the battle drew to a close in less than 2 hours.
