Ben 10

You will climb to the top of Weatherhead Tower in the stage The Tornado. During the stage, you will be doing a ton of platforming jumps and fight on stone platforms that don't really have side barricades, so the chances of falling are great at any time. You can die during the attempt due to a battle just as long as you don't fall off any of the sections during it. There are 4 things during the stage that you will want to watch out for that will cause you the most issues.

The first and most important one is the platforming itself due to the fixed camera as it can make it difficult to gauge where you are heading and landing when you make some of the jumps, especially to the smaller platforms. Make sure you are being patient and making your jumps properly so you don't have an unfortunate incident with landing on an edge and sliding off or missing completely.

The second one is the moving platforms as there many of them. Make sure that you are going to be able to get to them before they start moving or else you will more than likely fall since they move quickly. Also take a second before moving to the next section of stone to make sure it's not a moving platform in disguise as sometimes you might think it's just an attached stone for it to move as you're walking on to it.

The third one are the rock barricade spots with fans on the tower behind it. At various places along your climb, you will see fans on the tower and on the platforms in front of them there are a few rock barricades. The fans will turn on and off at different times causing strong wind gusts to blow in the open sections between the stone barricades that will knock you off the platform regardless of what you do. When you reach one of these spots, stand to the center to backside of the barricade and wait for the wind to stop before advancing forwards (if you stand closer to the front part there are times that the wind will knock you off even though you were behind the barricade).

The final one is the mandatory battles you face along the way. While thankfully there aren't that many of them, they are almost all fought on smaller platforms with no guards to keep you from falling off or getting knocked off. Try to stay in the middle of the fight area to avoid accidentally walking of or getting knocked off by the enemies.

Once you reach the boss Weatherhead Prime without falling off anywhere along the way up to him, the trophy will pop.
