As a Defense Digimon, Guardromon is useful for its ability to take a ton of hits without going down in battle. While its regular attack is pretty modest, Destruction Grenade adds a nice bit of range and some decent earth damage. Not only does Guardromon have a large health pool, but it also has the uncommon advantage of having no elemental weaknesses whatsoever, making it not only tough but also exceptionally versatile.
How to befriend Guardromon
To befriend Guardromon, you need to succeed in negotiation with one during a battle. The first place we found one was during Part 6 of the story, at the Free Battle location in the Second Island Area. Your goal during this negotiation is to answer a set of questions from Guardromon in a way that makes them sympathize with you. In this case, the best answers are generally the most confrontational options. If you want to skip any guesswork, though, the best answers to each possible question are as follows:
Once you answer enough questions correctly, you will have the choice of either asking for items or befriending Guardromon. While the latter option comes with a high chance of failure, there’s a good chance that attempting to negotiate at a later point in the story will result in more favorable odds.
