Talk:Galactus vs. Unicron/@comment-34727881-20180217175706/@comment-44702863-20200209162901

1. Unicron isn't a planet he is an actual god

2. Unicron only lost to Optimus and Megatron because Prime had the matrix

3. The matrix contains the power of Primus; the god of cybertronians, and Unicron's nemesis. Hence it is the only thing that can destroy him

4. Optimus is a descendent of the original 13 primes making him one of the strongest cybertronians of all time
