That... Isn't how the Metal Virus was portrayed in the comics - at all. The Metal Virus was probably one of, if not the, greatest threats Eggman unleashed on the planet, because it was an uncontrollable pandemic that had no cure, nor any way to remove it, save for literally going so fast that the Virus degraded.
If the Metal Virus was dumped on Bowser, or Jr, or Kamek, or all three at once, the fight would have instantly ended there. Immense exposure to the Metal Virus leads to immediate infection within seconds. By the time any of the three realized what was going on, they would have already been infected, and turned into mindless Zombots.
This is made even threatening by the fact that it spreads instantaneously to *anything* organic it comes into contact with. Even with "Plot Magic", there's no conceivable way that Bowswer, Jr, or Kamek would have been able to keep up with the spread of the virus. The moment any one of them became infected with it, it would have taken them - and their "plot magic" - out of the fight immediately, and this is even assuming that the trio would even know what kind of magic spell to use to counter the Metal Virus in a way that doesn't kill the host, something that the literal in-universe characters struggled with in trying to find a way to remove it safely.
The Metal Virus isn't a "power up", it was designed to turn whomever it infected into subservient "Zombots" to Eggman, except the Virus was too well designed, to the point where it evolved to not listen to any orders given by it's own creator. The Virus was a literal "If I use this, I win immediately" button for Eggman, which is why Death Battle immediately hand waved it away say "Well magic will nullify it so we didn't bother to include it in Eggman's arsenal in this fight" - it wouldn't have lead to a fun or interesting battle, so it was ignored, something DB is super guilty of doing constantly, because the show is more about the battle itself, rather than an actual realistic portrayal of who would win.
Prismsblade posted... Sages simulations are also useless because she has no data on Bowser or his forces. So how could she develop a strategy? And even if she could they dont guarantee anything.
So you know how we're saying DB undersold Sage? This is what we're talking about. Sage is the equivalent of Dr. Strange from Infinity War. She's a living, breathing, super computer that is capable of running an untold number of simulations and calculations in real time - something even DB admitted to in their assessment. She would have found the *one* way to guarantee success, even if it was the *only* way, relayed that information to Eggman and his Badniks, and it would have lead to victory, full stop. Her simulations are the equivalent to Strange's "I found the one way we win, Tony", moment in Infinity War.
While I'll give DB a pass, begrudgingly, for hand-waving the Metal Virus aside because it would have lead to a very quick, very boring, battle, there's literally no excuse for ignoring Sage's ability, and completely misinterpreting the reason why she wasn't able to find a solution to The End's threat due to her handicap, one that Eggman wouldn't have had in play for the sake of the battle.
That still could have lead to an impressive fight that would have played into Eggman's strengths over Bowser's obvious weaknesses. The simple fact is that, while this was a well animated and made fight, the team simply wanted Bowser to win from the get go, and bent the rules in his favor. But as others have said - that's how DB works, they go for the rule of cool, over the actual logistics of who would win.
Eggman should have won based on his merits and what he had at his disposal, but for whatever reason, Death Battle thought the fight would be more impressive and fun to watch if Bowser won, so that's how it went.
