IM just gonna simplify this for you, Also Im not even gonna bother answer your hypothetial "what if I was this character". I already told you they dont contribute anything
1 Ive made it pretty clear freiza an emperor IN fact I said that like Ten times already( exxageration but you get the point) and thats what hurts your argument. He was affecting the GALAXY.not just earth. He barey cared about it. King kai job is to watch over the galaxy. not just earth
2 How does being stronger than freiza make him an automatic threat to the galaxy. Freiza has an empire. dozens of men following his orders.. His job is selling planets. we saw that the androids where stronger than freiza. what did they do. they just ruined the earth . nothing about attacking the galaxies. for some reason you assume since Cell is stornger than freiza= he will automatically decide to attack the galaxy.Yes
3 No offense but what you said was ridicoulous and silly . .have you even watched super?Beerus? this entire argument was started about broly existing and nobody sensing his ki. Beerus was sleeping during the events of the dragonball/dragonball z.(he slept for 36 years goku was 34 when he met beerus). why would they sense him? and he had GOD KI( the ki that can only be sensed by those with divine status or being a god themself) which almost everybody who had it at that time either already knew him and expected him to keep sleeping(most of the kais) or never knew about him since again he was sleeping . As for Zeno . almost everybody knew about him? Yet no one knew about broly. You constantly comparison with Broly to these type of characters make no sense
3 How does being strongerr than freiza mean your automatically a threat to the galaxy?Cell didnt have an empire. Cell did not have any reason to be going around the galaxy taking over planet to planet and selling them. Him and the androids wanted to kill goku not take over the universe. cell is a bio android made to kill goku and avenge red ribbon army . freiza is an emperor who goes around trading planets for money. their goals do not match
