Multiple If Query Statements?

I have this code running, "B5 references a name."

(The code is all on one line, but this makes it easier to read)

=IFERROR(IF(QUERY({'Pokemon (NatDex)'!$A$2:$U;'Pokemon (Evolutions)'!$A$2:$U},"Select * Where Col1=1 and Col4 Contains '"&B5&"'"),CHAR(10004)),"x")&""&IFERROR(IF(QUERY({'Pokemon (NatDex)'!$A$2:$U;'Pokemon (Evolutions)'!$A$2:$U},"Select * Where Col18=1 and Col20 Contains '"&B5&"'"),CHAR(11088)),"x")

Right now, if it finds the B5 name listed on NatDex OR Evolutions sheet AND it's corresponding row = 1, it will display character 10004. Great! However the next If function becomes dependant on the first one, but I want it to work independantly.

I didn't use IFS because I want it to return different characters under the different conditions. I'm guessing the &""& connecting them makes the 2nd dependant on the first, but how else can you have multiple functions in one cell? If I change it to a comma it causes an error. If I wrap the whole thing in an OR function it returns "OR has no valid input data".
