Galactus is full power
Onslaught is full potential
Phoenix is full power
Tyrant is full power
Who wins Team 1, Team 2 or could go either way?
"Team 2 wins for the following reasons: 1. Phoenix can solo Galactus and Onslaught because The Phoenix (it could be the Phoenix Force or Jean Grey as The Phoenix) is virtually omnipotent and it represents life that has not been born yet and The Phoenix Force is what gave birth to Galactus and is what allowed him to live through the destruction of his previous universe before he was Galactus and was simply Galan and it is what allowed him to gain the power he has. 2. Phoenix's has limitless cosmic energy at her disposal even more than Galactus' who increases his own energy with his own energy source: The Power Cosmic which is potentially limitless while Phoenix's energy is already limitless and also allows her to use the energy for virtually any effect she desires but to Galactus' credit he can also use his power for virtually any effect he wants but not the extent that Phoenix can. 3. Galactus like Phoenix cannot die in this battle depending on where the battle is set for if it is in The Marvel Universe then neither can die for if one does the universe will be destroyed because they are both essential to the existence of the Marvel Universe because Galactus represents Equity and Balance while Phoenix represents life that has not been born yet so both are essential however Galactus can be defeated by being knocked unconscious because he has a physical form but has an abstract form but mostly uses his physical form so that he may exist in the physical world while Phoenix is a completely abstract being not possessing a physical form and cannot be harmed physically and only a being as high as Galactus or potentially higher can harm The Phoenix because his power is virtually unlimited and is enough to destroy certain abstract beings so it is logical that he can harm Phoenix but The Phoenix can destroy him. 4. Even if this Phoenix is Jean Grey or anyone or The Phoenix entity itself Galactus is not going to be able to defeat The Phoenix because even Rachel Summers as The Phoenix was able to defeat Galactus while trying to protect a planet from him and it should be noted that Rachel Summers has even worse control and mastery over The Phoenix than Jean Grey who is more powerful than Rachel Summers as The Phoenix so if it is Jean Grey or Rachel Summers as The Phoenix it doesn't matter because both of them are more powerful than Galactus, if it is The Phoenix Force itself than Galactus is losing even more terribly than before. 5. Any version of The Phoenix can destroy Galactus and if this is Dark Phoenix it is even more unfair to Galactus because Dark Phoenix is the most powerful version of the Phoenix as this is when the entity allows human emotions to cloud its judgement functionally granting it more powerful. As The Dark Phoenix, The Phoenix is evil and thirsts for power, destruction and control so it will not restrain itself against Galactus and would likely finish him off quickly. Even if it is not the Dark Phoenix any of its versions can destroy Galactus with not much problem. 6. Galactus can no longer absorb energy when he is full after absorbing the energy of an entire planet while The Phoenix can absorb the energy of entire suns and can use it to unleash devastating energy and its power will not deplete unlike Galactus' who's power will deplete greatly after wasting energy during battle. 7. If this was Tyrant in his original form then Galactus would have a tremendous battle as Tyrant's original power was nearly as powerful if not as powerful as Galactus himself and could have stalemated him and their battle led to the destruction of countless galaxies in the universe however if this is current Tyrant then he loses terribly to both Galactus and Onslaught individually. 8. Even the combined efforts and power of Galactus and Onslaught are not enough to defeat any version of The Phoenix as the weakest and most inexperienced host of The Phoenix: Rachel Summers was able to dominate Galactus who is more powerful than Onslaught by leaps and bounds so it is completely logical that any version of The Phoenix could defeat both Galactus and Onslaught as Onslaught is nowhere the power of both Galactus and Phoenix. 9. Adding Tyrant is truly unfair as The Phoenix by itself or herself could defeat both Galactus and Onslaught with not much problem and by adding Tyrant it is even more power for Galactus and Onslaught to handle however current Tyrant is weak compared to any of these beings even if he is at full power. 10. Phoenix could easily overpower Onslaught's reality warping abilities with her or its own which is much more powerful than Onslaught's or Galactus' as Phoenix can warp reality on universal levels. 11. Neither Onslaught nor Galactus has ever displayed power comparable to Phoenix's. While Galactus' power has been sufficient to destroy entire galaxies and Onslaught's power can hypothetically do so as well it is greatly diminished when compared to Phoenix who's power has been sufficient to destroy entire universes in the Marvel Omniverse.
