Bakugan: Defenders of the Core

The only thing you need to be worried about missing in this game are the treasure chests in exploration mode. Before about half of the missions in story mode, you have to run around on foot, navigating a map while avoiding robots and soldiers with flashlights. Each one of these stages has a set number of treasure chests. The chests always contain either a Vexos Pass Card, a Figurine, or an Ability Card.

While not all ability cards are obtained through treasure chests, the ones found in chests cannot be gotten anywhere else. Likewise, the Figurines cannot be found anywhere else. On top of that, you cannot replay exploration stages without starting Story Mode over from the beginning. If you press pause while in an exploration area, you can see the number of total treasure chests in the area and the number you have already found. Do not proceed to the stage exit until the pause menu says you have every treasure chest.

If you find every treasure chest in the game, you will get the Figurine trophy during the last exploration stage on your first playthrough. You will get the Ability Card trophy on your second playthrough when you unlock Maxus Helios (and thus unlock his personal ability cards).

Tips: Make sure you investigate every green dot on your radar. A green dot is always either core energy, a friendly human, or a treasure chest. If possible, try to go backwards from the beginning of the level. Several levels have core energy and treasure chests behind you from the start.

If you think you may have missed a chest on your first playthrough, don't freak out. You can get it on your second playthrough of Story Mode. However, if you miss a chest twice, you'll have to do Story Mode a third time, which would be a huge waste of time.
