"Well, they can be other colors due to regional variations and other causes.."

*She knows there are other factors to why a pokemon have a different color but she doesn't remember it and it isn't the time to discuss why pokemon have different colors. If it's a grenija, can probably take it but it's a water type, so perhaps it's better to take out her electrical type. What if it isn't a grenija at all? That would be bad, maybe she should observe and see... But if its fast someone can be hurt but maybe it's friendly...? Better to assume its hostile unless proven other wise, currently she should go for defensive instead of offensive just in case...*

"Kid, stay behind me..."

*Her voice sounds serious, if this kids get hurt it would be a stain on both her reputation and pride for failing to protect him.*

He backed off a bit, being careful about the potential threat in front of them. Pikachu electrifies himself, just in case Ash gives the order to attack. Ash then looks over at Hilda, he could tell by her expression that this was serious. He then smirked. "Say, why don't we see how good we could fair against this thing? I'm sure Pikachu might be able to handle it, right buddy?" Ash said to Hilda while also looking down at his partner. Pikachu nodded, getting himself ready.

*Pika Pi. Pikachu!*

The Greninja looked at the many Pokémon as it then retreated. While Ash was kind of disappointed that they didn't get to test out their strength, he was relieved as well. Ash was just about to call them off, but he suddenly realized something. He looked at the egg that his Hawlucha found and realized something: The egg had the color patterns of a Froakie, which could mean that the Hostile Greninja was its parent. "Maybe that was its Mother... Or Father.." Ash concluded
Wanda
*She wouldn't completely put her gaurd down yet but she would would take back her hands away from the pokeballs.*

*Hearing Ashs comment, she wanted to say I told you bit controlled herself, he's just a kid, he's got much to learn. This will probably be an important event for him, don't go picking up random eggs you see. This should be common sense, but kids aren't really bright most of the time. Maybe she should mention it...*

"If you see random eggs don't go picking them up, that's for both you and your pokemon. Parents are really really protective of there children and the result can end up being pretty nasty."

Ash crossed his arms behind his head. "I guess you're right. Sometimes it's hard to understand things. I'm still starting out," Ash replied. He looked towards the egg as his Hawucha comforted it. "Well now that that went down, what's going to happen with the egg? It's not going to take care of itself. And since the parent saw us with it, they might assume that we've eaten it or something, so I doubt they will return for it..." He began to say. After some thinking, he wasn't quite sure. Maybe it was best to return it to make sure the parent didn't worry. But after that idea came up, he had an idea. "Maybe I could ask if I could keep the egg and raise it! I've done it before, so it shouldn't be any different!"
